I’m trying to perform Named Entity Recognition (NER) using NLTK, SpaCy, and a dataset in PyCharm. However, I’m encountering an error related to a missing resource (punkt_tab) when tokenizing text. Here's the full error message:

Output

I have already downloaded the necessary NLTK resources in my script:

Necessary Nltk

Here’s the relevant code for my use case:

Code

What I Tried

  • Verified that punkt is downloaded successfully (nltk.download('punkt')).
  • Checked the folders listed in the error message to ensure punkt is present.
  • Searched online for any mention of punkt_tab, but couldn't find documentation for this specific resource.

My Questions

  • Is punkt_tab a separate resource from punkt? If so, how can I download it?
  • Could this error be caused by an issue in my NLTK or Python environment?
  • What steps should I take to fix this error and proceed with tokenization in PyCharm?
